The present invention concerns a method for concentrating dairy proteins. The method includes producing and using negatively-charged ultrafiltration membranes to achieve high hydraulic permeability with low sieving coefficients. The method thus yields good protein concentration at a fast rate.

A method for concentrating a substance in a milk product, the method including the steps of: feeding the milk product from a tank to a filtering device, filtering the milk product into a permeate and a retentate: such that the substance is concentrated in the retentate, circulating a first part of the retentate over the filtering device, feeding a second part of the retentate to the tank, repeating the circulations to thereby gradually increase a concentration of the substance in the milk product, and stopping the repeating when the concentration of the substance in the milk product has reached a predetermined value.

Asymmetric composite membranes and methods for their preparation are disclosed. The membranes comprise a cross-linked poly(vinyl alcohol) polymer coated on a film of cross-linked sulfonated poly(ether ether ketone) adhered to a sheet of hydrophilicitized microporous polyolefin. The microporous polyolefin is typically microporous poly(ethylene). The membranes have improved selectivity with the regard to the rejection of solutes in reverse osmosis and ultrafiltration applications.

The invention relates to a process for the purification of a neutral human milk oligosaccharide (HMO) from a fermentation broth, the process comprising the steps of: (i) separating biomass from the fermentation broth to provide a crude solution; (ii) treating the crude solution with: (a) a cation-exchange material; (b) an anion-exchange material; and (c) a cation-exchange adsorbent resin; thereby obtaining a purified solution containing the neutral human milk oligosaccharide. Further, the invention relates to a process for fermentatively producing HMO in a fermentation broth and purifying the HMO from the broth.

A process for manufacturing a demineralized milk protein composition, including a step (ii) of electrodialysis of a milk protein composition on an electrodialyzer, the unit cells of which have three compartments, and configured to substitute at least one cation by at least one hydrogen ion H+ in the milk protein composition to obtain an at least partially demineralized and acidified milk protein composition; a step (iii) of electrodialysis of the milk protein composition obtained in step (ii) on an electrodialyzer, the unit cells of which have three compartments, and configured so as to substitute at least one anion by at least one hydroxyl ion OH− in the milk protein composition.

The present invention relates to a method of producing an ideal whey protein concentrate. The whey protein concentrate has a pH in the range of 6.8-7.5 and 70-90% of the total proteins of the concentrate are whey proteins and 10-30% of the total proteins of the concentrate are caseins. The present invention relates also to an ideal whey protein concentrate and its uses in in reducing the total milk protein content and/or in increasing the whey protein content of a spoonable acidified milk product. In addition, the present invention relates to a method of producing a spoonable acidified milk product having high whey protein content but a reduced total milk protein content. The present invention relates also to a spoonable acidified milk product having high whey protein content but a reduced total milk protein content.

The present invention pertains to a new packaged, heat-treated beverage preparation having a pH in the range of 2.0-4.7. The invention furthermore relates to a method of producing a packaged, heat-treated beverage preparation and to different uses of the packaged, heat-treated beverage preparation.

The present disclosure provides compositions, methods, and uses concerning the enzymatic preparation of a fermented milk product.

A liquid treatment system, in particular for concentrating milk, and method therefor. The system includes an inlet configured to receive fresh raw milk; and a pressure vessel connected to the inlet. The pressure vessel is provided with a pressure system configured to realize a pressure of at least 10 bar in the pressure vessel. A reverse osmosis membrane is included for filtering the raw milk. A pump is provided for pumping the raw milk under pressure out of the pressure vessel and through or along the reverse osmosis membrane. A permeate outlet is provided for the separated water and a milk outlet is provided for the concentrated milk.

A butter with caramel is suggested, which is obtainable or obtained by: (a) separating whole milk into a skimmed milk fraction and a cream fraction by means of a separation step; (b) subjecting the cream fraction such obtained to a nanofiltration (NF) step and/or a reverse osmosis (RO) step, obtaining a NF/RO retentate and a NF/RO permeate; (c) subjecting the NF/RO retentate such obtained to a heat treatment step, in the process of which the sugar contained therein is caramelised at least in part; and (d) churning the caramelised NF/RO retentate such obtained in a manner known per se.
